Working with Label Formats as Graphics

The

^IS

(Image Save) and

^IL

(Image Load) commands are used to save a ZPL label format (including text and/or bar codes) in the printer’s DRAM, FLASH, PCMCIA, or battery backed up SRAM, as a special graphic image. This increases the throughput of a series of similar but not identical labels.

Instead of formatting each individual label completely, store the constant fields as an image (known as creating a template). Then, in subsequent label formats, commands are issued to recall that graphic image format and merge it with variable data.
